Abstract

Methods and apparatus are provided for providing PCI Express support. A device includes a hard-coded transceiver configured to support protocols such as Fibre Channel and the 10 Gigabit Attachment Unit Interface (XAUI), but the transceiver does not fully support PCI Express. Interface circuitry is configured to supplement or replace hard-coded transceiver components to provide PCI Express support. Interface circuitry allows PCI Express cores to operate with the transceiver that does not fully support PCI Express.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to supporting PCI Express. In one example, the present invention relates to methods and apparatus for implementing interface circuitry allowing PCI Express cores to operate with a transceiver not compatiable with PCI Express.[0003]2. Description of Related Art[0004]PCI Express is a low-cost, scalable, switched, point-to-point, serial I / O interconnection scheme that maintains backward compatibility with PCI. PCI Express provides a number of benefits over existing bus standards, including increased bandwidth availability and support for real-time data transfer services. PCI Express provides quality of service, power management, and I / O virtualization features. Quality of service and power management improve data integrity and allow control of power consumption. I / O virtualization allows data to be routed along logical routes, permits allocation of bandwidth to groups of devices, and provides ...
